together with a heap of the shells of some large bivalve, one of which 

 was polished and perforated for use as an ornament, were also found 

 among these bones. The stones of which the cist had been built, 

 the bones, and the objects accompanying them were so inextricably 

 mixed that it was impossible to tell which objects belonged to each 

 set of bones. Passing through the long axis of this mound was a 

 rubble-filled trench, 3 feet in breadth, dug down to the bedrock, 

 exactly similar in structure to those already 

 described. No interments were found at the 

 sides of this trench, which is shown in figure 

 23, E. 



Mound No. 6 A 



Momid No. 6 A, another of the group of 

 mounds adjoming the southwesterly bomid- 

 ary of Santa Rita, measured 18 feet by 15 

 feet at the base, by about 3 feet high at the 

 highest point, and was built throughout of 

 earth, large blocks of limestone, and limestone dust. The mound 

 rested directly on the limestone formation. Into this, near the cen- 

 ter of the mound, an oval excavation had been made (see C C, fig.

 tain the skull which was found within it. A ledgelike projection 

 was left at one edge of the excavation (see E, fig. 25), and just 

 beneath this rested the point of the jaw. A large heavy flag of lime- 

 stone (see D, fig. 25), from which a semicircular segment had been 

 chipped, was placed above the excavation opposite the lip, so that 

 the groove in the stone inclosed the neck and clamped the skuU
